IMPROVEMENT IN CANS AND BOXES FOR PRESERVING FRUITS, &c.

Specification forming part of Letters Patent No. 149,893, dated April21, 1874; application filed March 24,1874.

To all whom t may concern:

Be it known that I, EMILE TEYssoNNnAU, of Paris, France, have inventedcertain new and usefulV Improvements in Cans and Boxes for PreservingFruit, &c., of which the following isa specification:

This invention relates to the covers or caps of sheet-metal cans andboxes. Such covers have, in instances, been provided with tongues ortags projecting laterally from. and made in one piece with the cover, bytaking hold of which with pliers, pinchers, or a key, the covers can bewrenched or torn from the cans. To admit 0f this operation beingperformed with facility it is necessary that the cap should be unitedwith the can by a dat or horizontal soldered lapjoint; but to rendersuch an application of the cover or cap effective and readilyaccomplished, I find that it is necessary to provide means whereby boththe cover shall be guided and maintained in its place, and the solder orcement employed shall be prevented from extending inward beyond thelapped contiguous surfaces of the cap and can. To this en d I make thetongued cap with a depression or groove, forming on the under side ofthe cap a ridge or bead that, by its contour and size, is adapted to iitsnugly within the openin g in the can to which the cap is applied, thusconstituting at once a shoulder to guide and assure the cap yin itsproper position, and a stop or barrier to prevent the solder frompassing from between the overlapping surfaces of the cap and can intothe interior of the can.

The manner in which I carry my invention into effect will be readilyunderstood by reference to the accompanying drawings.

Figures 1, 2, 3, 4, 5, 6, 7, S, 9, 13 represent vertical centralsections of various styles of cans. Figs. 1b, 2b, 3b, 4ms, and 10 areplans of the cans in Figs. l, 2, 3, 4, 9, respectively.

Fig. 5 is a top viewof the cover detached.

The can is indicated by the letter A, the cover or cap by B. In everyinstance, as seen, the cover is provided with tag, tongue, or equivalentdevice, C, either in the shape of a flat finger or strip, as in Figs. 5and 7, which may be taken hold of `by a split key, as in- Fig. 12 at D,pliers, or other suitable instrument, or a prismatic loop or socket, asin Figs. 2, 3,

&c., to receive the correspondin gl y-shaped shank of a tool, such asshown at E, Fig. 11, or a cylindrical loop, as in Fig. et, to receiveany suitable tool, or to receive a bail, F, as in Figs. 1 and 6.

The cover, in all the instances given, overlaps the top of the canaround the opening therein, there thus being formed a fiat horizontaljoint, the solder being applied between the fiat contiguous surfaces ofthe cap and can that form the joint.

Now, in order to guide'and assure the cover in Vits position over theopening in the can, and also to prevent the solder from passing inwardlybeyond the horizontal lap, and into the body of the can, I Aform thecover, in every case, with a groove or depression, a, which follows thecontour of the opening in the case, and forms on the Linder side of thecover a guide ridge or bead, which its snugly within the opening'in thetop of the can, thus constituting a shoulder bearing against the edgesofthe can-top surrounding the opening, serving to enable the operator toat once put the cap accurately in place, serving as well to assure andmaintain the cap in such position. It also serves at the same time as astop or barrier to check and prevent the iniluX of solder, which wouldotherwise pass inwardly be- I tween and beyond the contiguous surfacesof the lap-joint.

In this feature is my invention mainly comprised, and, therefore, whileI do not broadly claim a tongued cover united with the top of the can bya horizontal joint,

I do claim as my invention- The combination, with the can or box, of atongued cover adapted to be united with the same by a iiat solderedjoint, and formed on its under side with a guide shoulder or rib,fitting the opening in the can to which the cover is applied, andoperating as shown and set forth.

In testimony whereof I have signed my name Witnesses EMTLE BARBAULT,AUG. Nnvcrr.
